Denny + + doc: clean up quotation style in NEWS. + * NEWS (2.5): For multi-character tokens in example grammar rules, + use "token" not 'token'. In English, use a consistent quotation + style; we might as well follow the precedent seen in info pages: + `quote' not "quote". + +2011-04-16 Joel E. Denny + + tests: pacify gcc 4.6.0's -Wunused-but-set-variable. + Reported by Jim Meyering at + . + * tests/actions.at + (Default %printer and %destructor for mid-rule values): Define + YYLLOC_DEFAULT so that it uses its Rhs argument. + +2011-04-16 Joel E. Denny + + glr.c: omit yyresolveLocations when locations are disabled. + This prevents gcc 4.6.0's -Wunused-but-set-variable from warning + about yyresolveLocations's local yyrhsloc. When locations are + enabled, there's no such warning because YYLLOC_DEFAULT then uses + yyrhsloc. Reported by Jim Meyering at + . + * data/glr.c (yyresolveLocations): Omit definition when locations + are disabled. + (yyresolveValue): Omit yyresolveLocations invocation when + locations are disabled. + +2011-04-16 Joel E.

The only other changes to + files that we use are copyright updates. + +2011-04-09 Joel E.
